I'm going to start posting details on the engine's features in a journal as I add them.

better documentation of how to use the tools outside of your PHP management system would be welcome

True, but at this point I've chosen to focus primarily on the game itself and can provide the toolset mostly only 'as is' (I've changed all the '<?'s into '<?php' though). I'm fine with how it works myself, but I've forever had this user-friendlier GUI concept laying around, which I'd like to implement one day.
